Improve <sys/cdefs.h>. Fix and use __RENAME (and lose ___RENAME --- two underscores should be enough for anybody). This was the point of this change, because I want to use __RENAME to support the two basename variants and the two strerror_r variants. Lose a bunch of macros that weren't being used. Lose three dead files from the DNS code. Change-Id: I3ef645c566b16a52217bc2e68c7d54b37c7c9522

Move bionic over to GCC's 'warning' attribute. This is a better solution than the old __warn_references because it's a compile-time rather than link-time warning, it doesn't rely on something that doesn't appear to be supported by gold (which is why you only used to see these warnings on mips builds), and the errors refer to the exact call site(s) rather than just telling you which object file contains a reference to the bad function. This is primarily so we can build bionic for aarch64; building libc.so caused these warnings to fire (because link time is the wrong time) and warnings are errors.
